try the garden clinic forum ... in case thiz doesnt pop in here ..
unless at least a half of your tree is defoliated.. i wouldnt worry too much about it ... presuming your tree isnt one foot tall ...
a few more facts about the tree will help ...
I'd like to see more pictures. Looks like a tortoise beetle larva of one kind or another. Or some sort of leaf beetle larva.
